Today will be a hot one. No, really hot.

Today the heat is really turned up.

Forecasters predict high temperatures this afternoon to reach or exceed the 100-degree mark in most of the Charlotte metro region, with uncomfortably high humidity as a sidekick.

It will be the last of the current heat wave, though.

A weak cold front is forecast later tonight, preceded by showers and thunderstorms late this afternoon and evening. And the front is expected to stall across the region for the rest of the week. That means a daily chance of afternoon storms and more tolerable afternoon temperatures – near the 90-degree norm for this time of year.

But we'll have to get through today first.

Forecasters expect afternoon highs to be in the low 100s in the area, with a heat index – the real feeling of the atmosphere, combining temperature and humidity – of 104 degrees in Charlotte and up to 107 degrees in Monroe and Rock Hill.

There has not been a 100-degree day this year at Charlotte/Douglas International Airport, although it reached 99 degrees on June 8 and 9. The temperature reached or exceeded 100 degrees six times last year, included two days with highs of 104, equaling Charlotte's all-time record.

Monday's highs reached the middle and upper 90s across the area, and authorities reported limited problems with the heat. Eric Morrison, a spokesman for Medic, Mecklenburg County's emergency medical service, said by late afternoon there were two apparent heat-related calls.
